One of the most troubling forms of global change is the alteration of natural landscapes, which leads to habitat loss, invasive species, and diminished biodiversity. In this talk, Carla D'Antonio from the University of California, Berkeley provides an overview of how human activity is having a profound affect on natural living systems. Dr. D'Antonio argues that while society does pay attention to impacts that affect agriculture or other economic activities, it must become aware of the widespread changes that are degrading natural habitats and reducing biodiversity.

Disease and invasive species make up one of the greatest threats to our forests and wetlands. In this informative lecture, Dr. Faith Thompson Campbell from the National Resources Defense Counsel discusses the magnitude of damage inflicted to natural habitats by invasive organisms and she highlights some effective ways control the problem. In addition, Campbell addresses the role of Congress in protecting forests and wetlands from future infestations.

About 20 stations have been established along the coastline of Antarctica, but only two are maintained year-round on the interior plateau: the Russian station at Vostok and the U.S. station at South Pole. In this entertaining and informative slideshow, Antarctic researcher Stephen Warren vividly illustrates the logistics of living at the South Pole. In addition, Dr. Warren discusses the results of the scientific research that brought him to the coldest place on Earth.

Dr. Stephen Schneider believes that in addition to the usual array of baffling scientific uncertainties, cultural, psychological and educational obstacles make these already difficult problems virtually unsolvable so long as we continue to deny their existence. In this lecture, Dr. Schneider, a professor from Stanford University and a public spokesman for global change issues, provides an overview of the science behind global change and discusses public resistance to its evidence. Dr. Schneider argues that in order to have a functioning democracy, citizens must start understanding and grappling with these pressing issues in global change.

"Chaos" and "fractals" are two terms signaling a scientific revolution that has taken place in the last 20 years. In this talk, NASA researcher Warren Wiscombe explains how ordinary objects and events such as snowflakes and snowboarding exhibit the characteristics of chaos. Additionally, Wiscombe describes how chaos and fractal theory can shed new light on long-standing scientific conundrums such as weather and climate, fluid flows, cells, and life itself.

Remote, or computer controlled aircrafts were developed for military uses but are now carrying instruments that contribute to our understanding of cloud-climate interaction - a critical issue in global climate change research. In this talk, Dr. David Sowle discusses the benefits of converting technology from military to civilian use and explains the particulars of using unpiloted aircraft to help understand climate change better.
